x in (-oo:+oo)
(2*x+3)/5 = (3*x+7)/4 // - (3*x+7)/4
(2*x+3)/5-((3*x+7)/4) = 0
(2*x+3)/5+(-1*(3*x+7))/4 = 0
(4*(2*x+3))/(4*5)+(-1*5*(3*x+7))/(4*5) = 0
4*(2*x+3)-1*5*(3*x+7) = 0
-7*x-23 = 0
(-7*x-23)/(4*5) = 0
(-7*x-23)/(4*5) = 0 // * 4*5
-7*x-23 = 0
-7*x-23 = 0 // + 23
-7*x = 23 // : -7
x = 23/(-7)
x = -23/7
x = -23/7
